I have curly hair. Look up 'the curly girl method'. It revolutionised my hair life. Don't use products with sulfates or silicones in them. Use a LOT of conditioner and leave some of your conditioner in. Put argan oil in your hair when it's wet. Wear it in a braid/pineapple at night, never brush it, use a wide tooth comb and trim the ends regularly. Just condition it a lot. Do olive oil treatments too, or coconut oil.
